Portable Network Graphics, is a file format that supports lossless data compression. A popular file type with web page because it can have a semi-transparent or transparent backgrounds. It's a type of raster image.
PNG is a raster image file format that was introduced in the
mid-1990s as a replacement for the GIF format. Since then, it has become one of the most
popular image formats used on the web and in various applications.
Key Features of PNG :
1. Lossless Compression: PNG uses a lossless compression algorithm that allows it to reduce
the file size of an image without losing any information. This makes it ideal for images
with transparent backgrounds or detailed text, such as logos and icons.
2. Transparency: PNG supports transparency, which means that it can represent images with
transparent backgrounds. This is particularly useful for logos, icons, and other graphics
that need to be integrated into different design elements.
3. High Color Depth: PNG supports high color depth, up to 16 million colors, making it ideal
for images with detailed and vibrant colors.
4. Compression Ratio: PNG's compression ratio is better than GIF but worse than JPEG, which
makes it a good choice for images that require a balance between quality and file size.
5. Support for 32-bit Colors: PNG supports 32-bit colors, which allows it to represent a
wider range of colors than other image formats like JPEG.
